AWNING.

Specification of Letters Patent.

Application filed June 13, 1905. Serial No. 266,040.

Patented May 8, 1906.

To ctZZ whom it may concern:

Be it known that I, FRANK ALANzo LEAR- NED, a citizen of the United States, and a resident of Chicago, in the county of Cook and State of Illinois, have made certain new and useful Improvements in Awnings, of which the following is a specification.

My invention is an improvement'in awnings; and it consists in certain novel constructions and combinations of parts hereinafter described and claimed.

In the drawings, Figure 1 is a side elevation of my invention.

front view of the winding-roller and adjacent parts. Fig. 4 is a vertical section on the line 4 4 of Fig. 1, and Fig. 5 is a detail of a form of awning of lighter construction provided with sin le-tube side arms.

11 the practical application of my invention I provide a frame comprising side arms A, each composed of a tube a of relatively large diameter, adapted to be hinged to the wall of a building, and a tube a of relatively small diameter, supported upon the large tube and provided with a longitudinal slot a A cross-bar Bconnects the free ends of the side arms, and upon the ends of the cross-bar are arranged the pulleys l) b. Rods a are arranged to slide within the tubes of, relatively large diameter, and rods a, provided with the lugs a for engaging the slots, are arranged to slide within the tubes of relatively small diameter, the free ends of the rods of the respective pairs being oined together and the respective pairs connected together by the cross-bars O. Awinding-roller D is journaled upon the wall of the building above the side bars A, and one of the ends thereof is provided with a sprocket-wheel d. I

A bearing F is secured to the building within convenient reaching distance from the pavement, and j ournaled in the bearing is a shaft f bearing a sprocket-wheel f 2 and providedwithout the bearing with a crank f a sprocket-chain f passin over the sprocketwheel f and the sprociet-wheel' d on the winding-roller.

Ropes a extend from the lugs a over the pulleys b b and are secured to the eyes a a attached to the building below the windingroller. The usual awning-cloth E is secured to the winding-roller and extends downwardly to the outer cross-bar C, to which it is secured in any suitable manner.

In operation the winding-roller is rotated Fig. 2 is a horizontal section on the line 3 3 of Fig. 1. Fig. 3 is a by means of the crank and sprocket-chain, winding up the awning-cloth and elevating the side arms. The tension of the awningcloth tends to force inward the sliding rods, this movement being allowed by the relaxation of the ropes a. When the awning-cloth is completely wound up, the sliding rods are within the tubes. When the awning is lowcred, the tension of the ropes a forces the sliding rods outwardly from the tubes, thus extending the side arms.

In Fig. 5 I have shown a form of side bar adapted for window-awnings or awnings of a similar character. In this construction the tube of relatively small diameter and the sliding rod therein are dispensed with, the larger tube being slotted and the rod therein provided with the lug. The frame is othervise similar in all respects to that shown in It will be evident from the description that my improved awning, although simple inconstructlon, is yet efiicient in operation and will not easily get out of order. The action of the ropes in extending the side arms is positive and is not dependent upon springs or weights, thus insuring always a proper extension of the arms.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. In an awning the combination of side arms, comprising each a tube of relatively.

lar e diameter adapted to be hinged to a bui ding, and a longitudinally-slotted tube of relatively small diameter supported on the first tube, a cross-bar connecting the outer ends of the side arms, pulleys at the ends of the crossbar, rods sliding in the respective tubes of the side arms, the rods in the tubesof relatively small diameter being provided with lugs for engaging the slots, a cross-bar connecting the free ends of the rods, a winding-roller j ournaled above the side arms and provided with a sprocket-wheel, ropes secured to the lugs and passing over the pulleys and secured at points below the windingroller, an awning extending from the windingroller to the outer cross-bar and means engaging the sprocket-wheel for actuating the winding-roller. V

2. In an awning, the combination of side arms, comprising each a longitudinally-slotted tube adapted to be hinged to a building, and rods sliding in the tubes and provided with lugs for engaging the slots, a cross-bar connecting the outer ends of the tubes, a cross-bar connecting the free ends of the rods, a flexible strand secured to the lugs and adapted to be engaged with a building, a windingroller journaled above the side arms and provided with asprocket-wheel, an awning extending over the winding-roller to the outer cross-bar, and means engaging the sprocketwheel for actuating the winding-roller.

3. In an awning, the combination of a frame provided with extensible side arms, each comprising a longitudinallyslotted tube adaptedto be hinged to a building, and a rod sliding in the tube and provided with a lug for engaging the slot, a cross-bar connecting the ends of the tubes, a cross-bar connecting the ends of the rods, pulleys journaled in the ends of the first crossbar, ropes secured to the lugs and passing over the pulleys and sewhereby cured at points above the side arms,

when the frame is lowered the side arms may be extended.

4. In an awning the combination of a frame comprising extensible side arms adapt- I ed to be hinged to a building each of the side arms comprisin a longitudinally-slotted tube, and rods s iding in the tubes and provided with lugsfor engaging the slots, a crossbar connecting the ends of the tubes, a cross bar connecting the free ends of the rods, pulleys on the ends of the first cross-bar, and a rope secured to the lugs, passing over the pulleys and secured at points above the side arms whereby when the frame is lowered the side arms may be extended.
